"Stores have an idea about the path [shoppers take], Walmart was once famous for doing things like putting like Band-Aids next to fishing hooks and things like that. Something you don't naturally associate, but once you see them there, it makes sense. So when people come in for something in one category, you can cross-sell, you can sell them something that compliments in the next product category by making sure they're right next to each other."

So there you go, we'd say next time you go to Kmart watch out for the 'cross-sell' but let's be honest, there's no hope for any of us.
